Hands on CERN contains
a lot of information about the world of particles, a world unfamiliar
to most of us. Even if we have difficulties to "see" the particles and
the interior of matter, they can be explored with modern detectors at
some specialised laboratories. Here you will be confronted with many
new words such as quarks, leptons, accelerators and detectors. It can
take a while to get familiar with all of them. There are essentially
two ways to use this material. Either you scan through the different
pages and images just to get a glimpse of how the interior of matter
can be explored, without having the ambition to understand all of it
or you take your time alternatively looking at the particle collisions
and studying the background material.
